Black Invention Myths, part I

Perhaps you've heard the claims: Were it not for the genius and energy of African-American inventors, we might find ourselves in a world without traffic lights, peanut butter, blood banks, light bulb filaments, and a vast number of other things we now take for granted but could hardly imagine life without.

Such beliefs usually originate in books or articles about black history. Since many of the authors have little interest in the history of technology outside of advertising black contributions to it, their stories tend to be fraught with misunderstandings, wishful thinking, or fanciful embellishments with no historical basis. The lack of historical perspective leads to extravagant overestimations of originality and importance: sometimes a slightly modified version of a pre-existing piece of technology is mistaken for the first invention of its type; sometimes a patent or innovation with little or no lasting value is portrayed as a major advance, even if there's no real evidence it was ever used.

Unfortunately, some of the errors and exaggerations have acquired an illusion of credibility by repetition in mainstream outlets, especially during Black History Month (see examples for the traffic light and ironing board). When myths go unchallenged for too long, they begin to eclipse the truth. Thus I decided to put some records straight. Although this page does not cover every dubious invention claim floating around out there, it should at least serve as a warning never to take any such claim for granted.

Each item below is listed with its supposed black originator beneath it along with the year it was supposedly invented, followed by something about the real origin of the invention or at least an earlier instance of it.

Traffic Signal
Invented by Garrett A. Morgan in 1923? No!
The first known traffic signal appeared in London in 1868 near the Houses of Parliament. Designed by JP Knight, it featured two semaphore arms and two gas lamps. The earliest electric traffic lights include Lester Wire's two-color version set up in Salt Lake City circa 1912, James Hoge's system (US patent #1,251,666) installed in Cleveland by the American Traffic Signal Company in 1914, and William Potts' 4-way red-yellow-green lights introduced in Detroit beginning in 1920. New York City traffic towers began flashing three-color signals also in 1920.
Garrett Morgan's cross-shaped, crank-operated semaphore was not among the first half-hundred patented traffic signals, nor was it "automatic" as is sometimes claimed, nor did it play any part in the evolution of the modern traffic light. For details see Inventing History: Garrett Morgan and the Traffic Signal.

Gas Mask
Garrett Morgan in 1914? No!
The invention of the gas mask predates Morgan's breathing device by several decades. Early versions were constructed by the Scottish chemist John Stenhouse in 1854 and the physicist John Tyndall in the 1870s, among many other inventors prior to World War I. See The Invention of the Gas Mask.

Peanut Butter
George Washington Carver (who began his peanut research in 1903)? No!
Peanuts, which are native to the New World tropics, were mashed into paste by Aztecs hundreds of years ago. Evidence of modern peanut butter comes from US patent #306727 issued to Marcellus Gilmore Edson of Montreal, Quebec in 1884, for a process of milling roasted peanuts between heated surfaces until the peanuts reached "a fluid or semi-fluid state." As the product cooled, it set into what Edson described as "a consistency like that of butter, lard, or ointment." In 1890, George A. Bayle Jr., owner of a food business in St. Louis, manufactured peanut butter and sold it out of barrels. J.H. Kellogg, of cereal fame, secured US patent #580787 in 1897 for his "Process of Preparing Nutmeal," which produced a "pasty adhesive substance" that Kellogg called "nut-butter."
George Washington Carver
"Discovered" hundreds of new and important uses for the peanut? Fathered the peanut industry? Revolutionized southern US agriculture? No!
Research by Barry Mackintosh, who served as bureau historian for the National Park Service (which manages the G.W. Carver National Monument), demonstrated the following:
Most of Carver's peanut and sweet potato creations were either unoriginal, impractical, or of uncertain effectiveness. No product born in his laboratory was widely adopted.
The boom years for Southern peanut production came prior to, and not as a result of, Carver's promotion of the crop.
Carver's work to improve regional farming practices was not of pioneering scientific importance and had little demonstrable impact.
To see how Carver gained "a popular reputation far transcending the significance of his accomplishments," read Mackintosh's excellent article George Washington Carver: The Making of a Myth.

Automatic Lubricator, "Real McCoy"
Elijah McCoy revolutionized industry in 1872 by inventing the first device to automatically oil machinery? No! The phrase "Real McCoy" arose to distinguish Elijah's inventions from cheap imitations? No!
The oil cup, which automatically delivers a steady trickle of lubricant to machine parts while the machine is running, predates McCoy's career; a description of one appears in the May 6, 1848 issue of Scientific American. The automatic "displacement lubricator" for steam engines was developed in 1860 by John Ramsbottom of England, and notably improved in 1862 by James Roscoe of the same country. The "hydrostatic" lubricator originated no later than 1871.
Variants of the phrase Real McCoy appear in Scottish literature dating back to at least 1856 — well before Elijah McCoy could have been involved.

Blood Bank
Dr. Charles Drew in 1940? No!
During World War I, Dr. Oswald H. Robertson of the US army preserved blood in a citrate-glucose solution and stored it in cooled containers for later transfusion. This was the first use of "banked" blood. By the mid-1930s the Russians had set up a national network of facilities for the collection, typing, and storage of blood. Bernard Fantus, influenced by the Russian program, established the first hospital blood bank in the United States at Chicago's Cook County Hospital in 1937. It was Fantus who coined the term "blood bank." See highlights of transfusion history from the American Association of Blood Banks.

Blood Plasma
Did Charles Drew "discover" (in about 1940) that plasma could be separated and stored apart from the rest of the blood, thereby revolutionizing transfusion medicine? No!
The possibility of using blood plasma for transfusion purposes was known at least since 1918, when English physician Gordon R. Ward suggested it in a medical journal. In the mid-1930s, John Elliott advanced the idea, emphasizing plasma's advantages in shelf life and donor-recipient compatibility, and in 1939 he and two colleagues reported having used stored plasma in 191 transfusions. (See historical notes on plasma use.) Charles Drew was not responsible for any breakthrough scientific or medical discovery; his main career achievement lay in supervising or co-supervising major programs for the collection and shipment of blood and plasma.

Washington DC city plan
Benjamin Banneker? No!
Pierre-Charles L'Enfant created the layout of Washington DC. Banneker assisted Andrew Ellicott in the survey of the federal territory, but played no direct role in the actual planning of the city. The story of Banneker reconstructing the city design from memory after L'Enfant ran away with the plans (with the implication that the project would have failed if not for Banneker) has been debunked by historians.

Filament for Light Bulb
Lewis Latimer invented the carbon filament in 1881 or 1882? No!
English chemist/physicist Joseph Swan experimented with a carbon-filament incandescent light all the way back in 1860, and by 1878 had developed a better design which he patented in Britain. On the other side of the Atlantic, Thomas Edison developed a successful carbon-filament bulb, receiving a patent for it (#223898) in January 1880, before Lewis Latimer did any work in electric lighting. From 1880 onward, countless patents were issued for innovations in filament design and manufacture (Edison had over 50 of them). Neither of Latimer's two filament-related patents in 1881 and 1882 were among the most important innovations, nor did they make the light bulb last longer, nor is there reason to believe they were adopted outside Hiram Maxim's company where Latimer worked at the time. (He was not hired by Edison's company until 1884, primarily as a draftsman and an expert witness in patent litigations).
Latimer also did not come up with the first screw socket for the light bulb or the first book on electric lighting.

Heart Surgery (first successful)
Dr. Daniel Hale Williams in 1893? No!
Dr. Williams repaired a wound not in the heart muscle itself, but in the sac surrounding it, the pericardium. This operation was not the first of its type: Henry Dalton of St. Louis performed a nearly identical operation two years earlier, with the patient fully recovering. Decades before that, the Spaniard Francisco Romero carried out the first successful pericardial surgery of any type, incising the pericardium to drain fluid compressing the heart.
Surgery on the actual human heart muscle, and not just the pericardium, was first successfully accomplished by Ludwig Rehn of Germany when he repaired a wounded right ventricle in 1896. More than 50 years later came surgery on the open heart, pioneered by John Lewis, C. Walton Lillehei (often called the "father of open heart surgery") and John Gibbon (who invented the heart-lung machine).

"Third Rail"
Granville Woods in 1901? No!
Werner von Siemens pioneered the use of an electrified third rail as a means for powering railway vehicles when he demonstrated an experimental electric train at the 1879 Berlin Industrial Exhibition. In the US, English-born Leo Daft used a third-rail system to electrify the Baltimore & Hampden lines in 1885. The first electrically powered subway trains, which debuted in London in the autumn of 1890, likewise drew power from a third rail. Details...

Railway Telegraph
Granville Woods prevented railway accidents and saved countless lives by inventing the train telegraph (patented in 1887), which allowed communication to and from moving trains? No!
The earliest patents for train telegraphs go back to at least 1873. Lucius Phelps was the first inventor in the field to attract widespread notice, and the telegrams he exchanged on the New York, New Haven & Hartford railroad in January 1885 were hailed in the Feb. 21, 1885 issue of Scientific American as "perhaps the first ever sent to and from a moving train." Phelps remained at the forefront in developing the technology and by the end of 1887 already held 14 US patents on his system. He joined a team led by Thomas Edison, who had been working on his "grasshopper telegraph" for trains, and together they constructed on the Lehigh Valley Railroad one of the only induction telegraph systems ever put to commercial use. Although this telegraph was a technical success, it fulfilled no public need, and the market for on-board train telegraphy never took off. There is no evidence that any commercial railway telegraph based on Granville Woods's patents was ever built. About the patent interference case

Refrigerated Truck
Frederick Jones (with Joseph Numero) in 1938? No! Did Jones change America's eating habits by making possible the long-distance shipment of perishable foods? No!
Refrigerated ships and railcars had been moving perishables across oceans and continents even before Jones was born (see refrigerated transport timeline). Trucks with mechanically refrigerated cargo spaces appeared on the roads at least as early as the late 1920s (see the proof). Further development of truck refrigeration was more a process of gradual evolution than radical change.

Air Brake / Automatic Air Brake
Granville Woods in 1904? No!
In 1869, a 22-year-old George Westinghouse received US patent #88929 for a brake device operated by compressed air, and in the same year organized the Westinghouse Air Brake Company. Many of the 361 patents he accumulated during his career were for air brake variations and improvements, including his first "automatic" version in 1872 (US #124404).

Air Conditioner
Frederick Jones in 1949? No!
Dr. Willis Carrier built the first machine to control both the temperature and humidity of indoor air. He received the first of many patents in 1906 (US patent #808897, for the "Apparatus for Treating Air"). In 1911 he published the formulae that became the scientific basis for air conditioning design, and four years later formed the Carrier Engineering Corporation to develop and manufacture AC systems.

Airship
J.F. Pickering in 1900? No!
French engineer Henri Giffard successfully flew a powered navigable airship in 1852. The La France airship built by Charles Renard and Arthur Krebs in 1884 featured an electric motor and improved steering capabilities. In 1900 Count Ferdinand von Zeppelin's first rigid-framed dirigible took to the air. Of the hundreds of inventors granted patents for early airship designs and modifications, few succeeded in building or flying their craft. There doesn't appear to be any record of a "Pickering Airship" ever getting off the ground.
US Aviation Patent Database, 1799-1909

Automatic Railroad Car Coupler
Andrew Beard invented the "Jenny [sic] coupler" in 1897? No!
The Janney coupler is named for US Civil War veteran Eli H. Janney, who in 1873 invented a device (US patent #138405) which automatically linked together two railroad cars upon their being brought into contact. Also known as the "knuckle coupler," Janney's invention superseded the dangerous link-and-pin coupler and became the basis for standard coupler design through the remainder of the millennium. Andrew Beard's modified knuckle coupler was just one of approximately eight thousand coupler variations patented by 1900. See a history of the automatic coupler and also The Janney Coupler.

Automatic Transmission/Gearshift
Richard Spikes in 1932? No!
The first automatic-transmission automobile to enter the market was designed by the Sturtevant brothers of Massachusetts in 1904. US Patent #766551 was the first of several patents on their gearshift mechanism. Automatic transmission technology continued to develop, spawning hundreds of patents and numerous experimental units; but because of cost, reliability issues and an initial lack of demand, several decades passed before vehicles with automatic transmission became common on the roads.

Bicycle Frame
Isaac R. Johnson in 1899? No!
Comte Mede de Sivrac and Karl von Sauerbronn built primitive versions of the bicycle in 1791 and 1816 respectively. The frame of John Starley's 1885 "safety bicycle" resembled that of a modern bicycle.

Cellular Phone
Henry T. Sampson in 1971? No!
On July 6, 1971, Sampson and co-inventor George Miley received a patent on a "gamma electric cell" that converted a gamma ray input into an electrical output (Among the first to do that was Bernhard Gross, US patent #3122640, 1964). What, you ask, does gamma radiation have to do with cellular communications technology? The answer: nothing. Some multiculturalist pseudo-historian must have seen the words "electric" and "cell" and thought "cell phone."
The father of the cell phone is Martin Cooper who first demonstrated the technology in 1973.

Clock or Watch (First in America)
Benjamin Banneker built the first American timepiece in 1753? No!
Abel Cottey, a Quaker clockmaker from Philadelphia, built a clock that is dated 1709 (source: Six Quaker Clockmakers, by Edward C. Chandlee; Philadelphia, The Historical Society of Pennsylvania, 1943). Banneker biographer Silvio Bedini further refutes the myth:
Several watch and clockmakers were already established in the colony [Maryland] prior to the time that Banneker made the clock. In Annapolis alone there were at least four such craftsmen prior to 1750. Among these may be mentioned John Batterson, a watchmaker who moved to Annapolis in 1723; James Newberry, a watch and clockmaker who advertised in the Maryland Gazette on July 20, 1748; John Powell, a watch and clockmaker believed to have been indentured and to have been working in 1745; and Powell's master, William Roberts.
Silvio Bedini, The Life of Benjamin Banneker (Baltimore: Maryland Historical Society, 1999)

Clothes Dryer
George T. Sampson in 1892? No!
The "clothes-drier" described in Sampson's patent was actually a rack for holding clothes near a stove, and was intended as an "improvement" on similar contraptions:
My invention relates to improvements in clothes-driers.... The object of my invention is to suspend clothing in close relation to a stove by means of frames so constructed that they can be readily placed in proper position and put aside when not required for use.
US patent #476416, 1892
Nineteen years earlier, there were already over 300 US patents for such "clothes-driers" (Subject-Matter Index of Patents...1790 to 1873).
A Frenchman named Pochon in 1799 built the first known tumble dryer — a crank-driven, rotating metal drum pierced with ventilation holes and held over heat. Electric tumble dryers appeared in the first half of the 20th century.

Dustpan
Lloyd P. Ray in 1897? No!
While the ultimate origin of the dustpan is lost in the mists (dusts?) of time, at least we know that US patent #20811 for "Dust-pan" was granted to T.E. McNeill in 1858. That was the first of about 164 US dustpan patents predating Lloyd Ray's. See the dustpan patent list.

Egg Beater
Willie Johnson in 1884? No!
The hand-cranked egg beater with two intermeshed, counter-rotating whisks was invented by Turner Williams of Providence, Rhode Island in 1870 (US Patent #103811). It was an improvement on earlier rotary egg beaters that had only one whisk.

Electric Trolley
Did Granville Woods invent the electric trolley car, the overhead wire that powers it, or the "troller" wheel that makes contact with the trolley wire, in 1888? No!
Dr. Werner von Siemens demonstrated his electric trolleybus, the Elektromote, near Berlin on April 29, 1882. The vehicle's two electric motors collected power through contact wheels rolling atop a pair of overhead wires. The earliest patentee of an electric trolley in the United States appears to be Eugene Cowles (#252193 in 1881), followed by Dr. Joseph R. Finney (#268476 in 1882) who operated an experimental trolley car near Pittsburgh, PA in the summer of 1882. In early 1885, John C. Henry established in Kansas City, MO, the first overhead-wire electric transit system to enter regular service in the United States. Belgian-born Charles van Depoele, who earned 240+ patents in electric railway technology and other fields, set up trolley lines in several North American cities by 1887. In February 1888, a trolley system designed by Frank Sprague began operating in Richmond, Virginia. Sprague's system became the lasting prototype for electric street railways in the US.

Elevator
Alexander Miles in 1887? No!
Was Miles the first to patent a self-closing shaft door? No!
Steam-powered hoisting devices were used in England by 1800. Elisha Graves Otis' 1853 "safety elevator" prevented the car from falling if the cable broke, and thus paved the way for the first commercial passenger elevator, installed in New York City's Haughwout Department Store in 1857. The first electric elevator appeared in Mannheim, Germany in 1880, built by the German firm of Siemens and Halske. A self-closing shaft door was invented by J.W. Meaker in 1874 ("Improvement in Self-closing Hatchways," US Patent No. 147,853). See Elevator Timeline
Fastest Computer/Computation
Was Philip Emeagwali responsible for the world's fastest computer or computation in 1989? Did he win the "Nobel Prize of computing"? Is he a "father of the Internet"? No!
The fastest performance of a computer application in 1989 was 6 billion floating point operations per second (6 Gflops), achieved by a team from Mobil and Thinking Machines Corp. on a 64,000-processor "Connection Machine" invented by Danny Hillis. That was almost double the 3.1 Gflops of Emeagwali's computation. Computing's Nobel Prize equivalent is the Turing Award, which Emeagwali has never won. More...

Fire Escape
Joseph Winters in 1878? No!
Winters' "fire escape" was a wagon-mounted ladder. The first such contraption patented in the US was the work of William P. Withey, 1840 (US patent #1599). The fire escape with a "lazy-tongs" type ladder, more similar to Winters' patent, was pioneered by Hüttman and Kornelio in 1849 (US patent #6155). One of the first fire escapes of any type was invented in 18th-century England:
In 1784, Daniel Maseres, of England, invented a machine called a fire escape, which, being fastened to the window, would enable anyone to descend to the street without injury.
Benjamin Butterworth, Growth of Industrial Art, 1888
By 1888 the US had granted 1,099 patents on fire escapes of "many forms, and of every possible material" (Butterworth).

Comments

I'm currently a Research Fellow for UC/Wolfram Research GmbH, working with a team to take a concept still referred to as being "Theoretical" by academic and professional journals. To be brief, what we are doing is developing and designing a real-world machine incorporating an "exotic" set of technologies-- before they are, by accepted definitions-- even proven as possibilities. Sounds as if we are going from proof-to-product without proof or even prototype? Sure it does.
What we have in fact done is apply a conceptual basis for a craft designed at least 90 years ago by German and Hungarian industrial engineers. No African-Americans. No Africans at all. Not even to mop the floors. We still employ none. Not because we are White. Because no blacks ever interviewed were of the caliber and thinking level to be of use.
And this has led to the attempts to impose sanctions on the project, impede its development, and block assignment of production contracts with the industries globally which are enthusiastically poised to begin production, possibly as early as 2024. We have been bluntly told if "minority" labor is not recruited and placed in a number of key departments (which do not even exist yet) the machines will NEVER be built inside the United ?States-- and if it is built without those same "minorities" in other countries, it will not be allowed to be sold or marketed there.
